corporation of Delaware Application February-1s, 1937, serial No.125,52: .r'll Cla ims. (C 180-69) shutters have beenapplied in variousways and have added to the cost of the vehicle. In many,

- instances the purchaser does not desire a; shutter on his vehicle andwould prefer the saving in '25 comprises a U-shaped supporting iron, thearms of the U being -U-shaped in cross section. 'The radiator core isfastened to the rearmost flanges 'of the U-sectioned arms while thefront face thereof is spaced from the forwardmost flanges thereof toleave a pocket or space between the core and the front flanges. Betweenthe front flanges and the core a frame containing a radiator is adaptedto be slid from the top, and to prevent rattle of the parts the sides ofthe frame are provided with suitable spring clips to press against thebase of the U. To enable the shutter frame to be slipped in place, theinterfering parts of the radiator shell, etc. are first removed.

On the drawings Figure 1 shows in side view a part of an auto motivevehicle showing the invention applied.

vFigurei l is an enlarged detailed sectional view on the-line 9- -ll'ofFigure 8.

Referring to the drawings, the numeral 2 indicates the vehicle as awhole. The vehicle has the usual hinged hood 4, radiator shell 5, cowl6, l instrument board 8, dashboard l0,-interna1 combustion engine 12,provided with a clutch housing l4 to enclose the usual clutch relatedwith the transmission inclosed in the housing l6 and operated from theshift lever [8. The engine I2 10 has the oil pan 20 and the head 22 andis equipped with the usual water cooling system, part of the .pipesofwhich are shown at 24. On one end of the crankshaft there is mounted theusual lower fan pulley 25 over which there is trainedthe belt 28 whichin turn runs over the upper fan pulley 30. to drive the fan 32 and theimpeller of the water pump, 34. The pump 34 forces the water through thepiping 24 into the upper. tank 36 of the radiator 38, the radiator beingindicated in 0 dotted lines in Figure 1.

The radiator 38 is rigidly mounted in the U- shaped frame or harness 40which'is best shown in Figure5. ,The frame or harness 40 is of generallyUform and has the upstanding legs 42 and base 43. The base 43 is mountedon the transverse member 45 of the frame 41; A suitable rubber block 5|is positioned between-the frame and transverse member 45 so that the Uframe 40 is resiliently mounted at a single point. "30

Referring to Figures 2 and 5 it-will be noted that each of the uprightlegs 42 of .the U harness ,or frame are U -shaped in cross-section andcomprise the web 44, the rear flange 4B and the front flange 48.Suitable braces extend across :35 the front of the frame 40 from one leg42 to the 8 other rigidly to brace the construction. The harness 40 maybe L-shaped in cross-section and have the front flange 48 only. Theparts so far described arein general conventional. 40

Referring toFigure 2, it will be noted that the core of the radiator 38is rigidly secured to the flange 46 by the angle iron straps 52 whichhave onewingwelded to the outside of the flange 46 and the other wingwelded to' the side of thefi45' radiator core rigidly to hold theradiator core 38 in place.- One angle iron 52 is used at each 'side' ofthe vehicle; The front face 54 of the radiator core is spaced aconsiderable distance from the front web-48 of the arm 42 so that apocket or '50 space is provided between the front face. of the radiatorcore and the flange 48. In this space there is slid the shutter frame 56containing the conventional type of shutter. The vehicle as it leavesthe factory has no shutter in place, and in by means of the pivots 60the shutter blades 62..

All of the shutter blades 52 are connected to the longitudinal rod 64 bymeans of theiipivots3'66 secured to inturned wings 61 on the blade ends.A spring 68 has one end secured to the frame 56 and the other end 12'fa'stened'to the -bar'6f4. so that the spring constantly urges the barand the blades 62 to the open position shown inFigures 2 and t. At theright end of the frame 56 in Figure 2 there is mounted a stud 14. To thelower end of this stud there is securedthe lever 16, pivoted at 18 to alink 80, pivotedat '82 to the bar 64. The upper end of the stud 14 hassecured theretothe lever arm 84 which in turn has a stud 86 mountedthereon. -.The stud 86 has an opening therein for the reception of theend of the wire 88, and "a screw 90 screw threaded into the top of thestud rigidly binds the end of the wire 88 to the stud 85. Theoperatingwire .88 passes through a casing 92' to the dashboard 8 Where it isoperated from the handle 64.

The manner in which the casing 92 is mounted in the vehicle is bestshown'in Figures 5' andfi. The'hood side 96 is preferably rigidly but.remo-vably secured to the side of the vehicle and is not hinged as isthe customary practice. The upper part of the side 95 is inwardly bent"at 98 and has secured under the flange 98 the fastener 100, secured tothe flange 98 by means of the bolt and nut 162. The flange 98has a sounddeadening strip Hi3 secured in a 'rabbet at the flange edge, the stripills-serving as a rest for the edge of the hinged section 4 of the hood.At the angle between the parts 96 and 98 the fastener I 60 is rounded tohold the casing 92 snugly inthe corner. Preferably two such fasteningdevices'as shown in Figure 6 are used to hold the casing in place.Referring toFigures 3 and 4, it will be seen that the side of the frame56 is provided with spring clips :04 at its top and bottom part, thespring clips being secured at one end as at 106 by welding to the frameside. At its free end H18 the spring has a slightly curved part whichmerges into the central arched part H0. When the frame 56 is slid inplace into the U-shaped harness between the front face 54 of the core 38and the flange 48, the spring clips I04 Will be flattened somewhat tocause the turned end I68 to move slightly over the edge of the frame 56.This compressing of the spring clips I04 will prevent rattle of theframe and hold it inposi'tionj Under the arched part of the spring clipsI04 the angle irons H2 are provided. One wing-of the angle ironissecured to the'side of th'e frame 56 while the other wing has a sounddeadening material H4 secured thereto and a'buts" against the inside ofthe flange 4'8 to prevent rattle and movement of the parts. Theoperation of the shutter =-or Figures "2; 3, and 4 is as'followsiassuming the parts to'be-in "the position shown or inthe'open positionof the shutterandthe operator wishes to close' the'shutter to reduce theentrance of air, theoperator will pull on theknob'94 atthednstruniehtboard which will pull the Wire 88 to swing the lever 84 tothe right in Figure 2 which in turn will throw the lever 16 to the leftto push the link 80 and operate the bar 64 to swing all of the shutterblades 62 on their pivots 60 to close the shutter. This movement willincrease the tension on the spring 68. A suitable mechanism such as aspring operated toothed and notch connection (not shown) is provided atthe dash at the knob 94 to hold the shutter in closed position. When the,operator wishes to close the shutters he will release the connection atthe dash and allow the spring-.68. to pull the shutters to the openposition shown in Figure 2.

I In Figure '5 the blades 62 of the shutter are 'shownasi'extending tothe base 43 of the harness "40.

:where the radiator extends substantially to the bottom of the harness,the longer shutter as shown at 62 in Figure 5 is used.

In the species of Figures '7, 8, and 9, the shutters are shown asoperating in a different manner, nthat is; the spring 68' always tendsto pull the .shuttersto closed instead'of open position. 'The blades 62'are pivoted on the studs at 66 and are interconnected in the usual wayby means of the bar 64 which is fastened to wings or fingers 6'! on eachshutter blade 62'. The frame 56' of the shutter has an opening H1 at itstop and through the opening there pass the pins 69 as shown in Figures7-9. The pins pass through spacers H and are rigidly secured to the bar54. Confined between the heads of the pins 69 and theispacers Tl thereis the arm 13 which extends out over the front of the frame and isdownturned at 75 and has secured to the downturned part the stud 11which in turn has secured thereto the end of the wire 88, the wire beingsecured in'place bymeans of the screw 6!) threaded into the stud 'end...A' spring 68' is secured at one end to .'a finger '19 on the arm 13and'at its other end to 'a'rfinger '8! on the bracket secured to theframe 56%.
